Abstract

The present invention relates an acidic aqueous solution suitable for the pickling of stainless steel grades that comprises accelerators based on watersoluble inorganic compounds comprising at least one nitrogen atom in an oxidation state in the range of -2 to -1/3. The present invention further encompasses a process for the pickling of stainless steel that makes use of a pickling solution comprising the above-mentioned accelerators.
